Sentinel-2

Purpose

This page will outline Sentinel-2 as a high-resolution optical imagery source for vegetation, land cover, water, and change detection workflows.

Outline

• What Sentinel-2 contributes to Earth observation workflows.
• Spatial, temporal, and spectral strengths at a high level.
• Common quality concerns such as clouds, shadows, haze, and scene edge artifacts.
• How surface reflectance, cloud masking, and compositing affect analysis choices.
• Workflow relevance for monitoring vegetation, urban growth, agriculture, and water extent.
• Engineering implications for scale, tiling, band selection, and time-series processing.
• Access patterns across Earth Engine collections, STAC metadata, and cloud-hosted archives.

Later Examples

• Seasonal vegetation composite outline.
• Cloud-masked change detection workflow sketch.
• Comparing Sentinel-2 with Landsat for regional monitoring.
